Norton Abrasives - St. Gobain, ProSand 9 in. x 11 in., Sanding Sheets 400G - 20 Pack

The product is excellent is you want a grit only slightly finer than 280 grit. This is mislabeled as 400 grit, when the back of the sheets indicate P400 grit, which is to FEPA / EURO standard. The abrasive in this P400 paper is 42 micron, where a 400 grit is 30 micron. As a comparison, a 280 grit paper is 45 micron. Norton needs to revise their packaging to make sure the labeling on the package is clear.

The longevity and consistency of this paper beats the pants off of most others. It's probably even just a hair better than equivalent 3M WetOrDry paper. Value of buying the big pack is excellent. Would buy again (although probably not for years as the 20 sheet will take quite a long time to go through with how long a sheet lasts!)

I use this for painting with pastels. It's absolutely fantastic as a lesser expensive way to get the surface you need. While sanded pastel paper is thicker, this isn't. It's much thinner. However, the pastel covers the surface. You could mount the paper first if you want a thicker or harder board. It's definitely worth a try for all the practice paintings. I have even framed many of them on this paper.

This product is packaged as 400 grit sandpaper. It is actually P400, which is not what I need.

Great value and convenience of home delivery for lower prices!
